STONE-GATHERING MACHIE.

Application filed october s, 191s;

To all whom t may concern:

Be it known that .1, Jol-1N W. ScHRonDnn, a citizen of the United States, residing at Zurich, in the county of Blaine and State of Montana, have invented new and useful Improvements in Stone-Gathering Machines, of which the following is a specification.

This invention relates to improvements in stone gathering machines and the object of the invention is to provide a machine for clearing fields of stones.

Another object of the invention is to provide means for cultivating the ground an killing weeds while gathering the stones;`

Among other features the invention includes a rake for forcingthe stones along inclined bars, a receiving hopper for .receiving the stones from the rake, means for raising the hopper when desired anda box'for receiving the stones from the hopper.

vAnother object of the invention is to provide l a device of this character which is simple and durable in construction, reliable and efficient in operation and one which can be manufactured and placed upon the market at a minimum cost.

The invention also consists 'in certain other features of construction and in the combination and arrangement of the several arts, to Abe hereinafter. fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims. f

In describing my invention in detail, reference will be had to Vthe accompanying drawings wherein vlike characters denote like or corresponding parts throughoutl the several views, and in. which':-

`Figure 1 is a sideV view of the invention.

These plow bars are larranged in pairs with the transverse -rods 25 connecting two pairs together. connected with the cross bar 21 by means of a bushing 27. The lower ends of each pair ofplow bars have secured thereto a plow 28. This plow is of substantiallytriangular shape withl its heel 29 slightly lower than its point so that the heel will enter the 'ground to a greater extent than the point.- A track bar 30 isv located above and suitably vconnected with each of the outermost plow bars. The upper end of each of the track bars is upturned as at 31 and its lower ondis inclined and extends in front of the plow. 32,r indicates the upper track bars secured to the lower track bars 30 by means of the standards 33. These upper track bars are each provided with a pivoted gate 34 havingits free end normally engaging ythe Each pair of plow barsis upper face of the lower track bar, d'ue to the action off gravity'.

This cross bar is carried by a pair of pitman rods) having their lupper ends connected by links 40 with the are further connected together by the transverse bar 4land a bracket 42 securedto each of 'the outermost ,rake bars carries a roller 43 which' is adapted tovengage with. the

track bars,Y before described.

Eachof the links 40. is provided with a dog 4l which has roll-er 42. on one end eni gaging with the' inner circumference of the l the yupper bars. 82"..

Thismovement through the. pitinen 3.9 will cause the rake to move up the trank bars 30.. In this movement the` rollers 43 .will strike the gates 34and lift. the same so. as. toper-InittherolL. ers to. .pass by. The as; to engage with the dogs 4l to :release the same. from therecesses ltwhen the ril-ke reaches the ends of thestrackbars...

Springs 45 connected with saidlinks. willthen draw the links andpitmen to a noIInal-pos1t1-on-and 1n this action they rake will lpass downwardly and owing to the rollers 43 striking the. upper surface of the gate said rake willbe .causedto travel over When they reach. the
